Iron Deficiency Calculator

Calculation of iron deficit can be useful before iron infusion. Each infusion cannot exceed 300mg. Be careful to fill in the hemoglobin levels in g/dl.

Ganzoni's formula: Deficit = Weight * (Target Hb - Patient Hb) * 2.4 + Reserves

Iron deficiency: how to recognize it?

Worldwide, approximately 25% of the population suffers from an iron deficiency. So it's a more common situation than you might think. Essential for the proper functioning of the body, iron must be consumed in sufficient quantity to fulfill its functions. According to those affected, the signs of iron deficiency vary from fatigue to pallor, including difficulty concentrating.

What is the role of iron in the human body?

From the family of mineral salts, iron is a trace element naturally present in the human body at approximately 4 g. To compensate for losses throughout the day, an adult male needs to take 11 mg per day. For a woman, the figure can go up to 16 mg per day during menstruation, due to blood loss.

Iron plays an essential role because it is found in the hemoglobin of red blood cells present in the blood. Thus, it ensures the transport of oxygen from the lungs to all the tissues of the body. Being also a component of myoglobin, it participates in the storage of oxygen in the muscles.

What are the causes of iron deficiency?

Women are the most prone to iron deficiency, especially in the event of heavy periods, intermenstrual bleeding, or during pregnancy. Indeed, iron needs increase in pregnant women who must ensure both their own intake and that of their baby. Iron needs can reach 30mg per day.

Inadequate intake in the diet is the second most common cause of the iron deficiency. It is in products of animal origin that we find heme iron, which is best absorbed by the body. However, people following a vegetarian or vegan diet cannot have access to this type of iron. Supplementation may then be appropriate.

Long-term athletes (marathons, cross-country skiing, trail running, cycling, etc.) also increase their risk of iron deficiency. Indeed, “aerobic” sports require a large and constant influx of oxygen to the muscle tissues. Eventually, the number of red blood cells may decrease, causing an iron deficiency called iron deficiency anemia
